How fat do you have to be to become bulletproof? Why do people have eyebrows? Can eating green potatoes really kill you? How quickly could you turn into a fossil? And why do pineapples have a hard, spiny skin that would discourage eating them? This book is packed with lighthearted but real scientific wisdom from the "Last Word" column of New Scientist, in which questions submitted by readers are answered by the magazine's editors.

"This [book] proves there really is no such thing as a stupid question.... The conflagration of trivia, knowledge, anecdote and humor should entertain just about anyone."—Publishers Weekly
